A guy with too many tubes
I've been using this for about a week, and I'm very impressed. I'm still using the stock wallwart power supply through RPi micro-USB to power both the RPi and the Boss, but am just a couple of connectors away from a separate regulated power supply for the DAC. But as is, it's quite impressive -- and not just for the low price! In an absolute sense it's seriously good. Bass is better than I've ever had out of CDs, but the rest is better too.
I soldered the parts last night for this PCB ultra low-noise regulated supply. Hooked up a nominal 7v xformer and measured 5.00 Vdc -- alrighty then! Only then did I realize that the jumpers I had from a DIY computer project were not going to work to go from power supply board to DAC pins -- waiting now for those to arrive. I'm told the improvements are substantial.
But with a good start on a FLAC library from CDs using Exact Audio Copy, I have a lot to listen to now in my family room setup. I like this well enough to build two more for my "real" audio systems (workshop, basement mancave). Even with the dedicated power supply it's well under $200. You could spend a lot more without matching this performance. I'm not sure if there are problems with running multiple units on the same wi-fi system, but it's probably a matter of properly naming each one. Storage is cheap enough to duplicate files in different locations (backups!!!) and forget wifi streaming.
